I INDEX BINDER Filed Dec. 11, 1929 INVENTOR.

ATTORNEY Patented Aug. 11, 1931 fiTES FATE? GFFHCE ANTONE J. CARDOZA, OFOAKLAND, CALIFORNIA INDEX BENDER Application filed December 11, 1929.

'10 Binding of magazines, and other publications in temporary binders ofvarious types, is well known. For purposes of de scription of thisinvention, the use thereof in connection with telephone directories isused as an example, though the invention may be used with equal facilityfor magazines and other publications.

These directories or publications usually comprise printed sheets boundby stapling or sewing at their rearward edge, and having a flexiblecover. For ease of reference to these directories it is desirable toprovide an index member between the several volumes. Heretofore, it hasbeen customary to bind such publications in temporary binders of theremovable spring bar type, and in so doing the spring bar is passedlongitudinally between the pages and secured in the well known manner ofinserting the ends of the 39 spring bar in the terminal of the binder.The objection to this form of binder is that if the publications arebound tightly, side by side, in the bind r, the reading matter adjacentthe bound edge is obscured when the binder is opened; and if thepublications are bound loosely, side by side, the bound edge turns onthe binding rods and rides up on the abutting publication when thebinder is opened, so that when the binder is again closed, there is africtional resistance between the bound edge of one publication and theside of the abutting publication which prevents the binder from closingfiat as it is intended to do. I have found that by the use of additionalrods between the publications, the bound edge or fold is maintained inits proper position within the binder. I further utilize the rodsbetween the publications as supports for index sheets, and by so doing Iprovide an index sheet Cir Serial No. 413,234. I' 'I which may bereadily adjusted longitudinally of the binder, whereas if placed on the'rod engaging the publication, such adjust ment is apt to tear the pagesof the publicai tion. This structure also permits the insertion of theindex at the front of each publication instead of intermediate thereof,and further provides an index which may be entirely removed from therods for purposes of changing when the publication within the binder ischanged. These index sheets should have sufiicient grip on the rods tosecurely maintain them in placement, but should be yieldingly slidablelongitudinal of the rod for purposes of adjustment in" offsetrelationship relative to each other or removal entirely from the binderfor changing. By providing an ovoidal loop at one end of the index sheetto engage the spring, rod, a frictional grip on the rod is obtained onthe minor axis while the major axis provides sufficient play to permitthe index sheet to be yieldably mounted on the rod. The ovoida-l loop ofthe index sheet also extends into the trough between bound edges of thepublications and thus prevents the bound edges from riding up the sideof the adjacent publication, when the binder is opened and acts as aguide to return the. bound edge of the publication to its proper 39place when the binder is closed after having been opened.

()ne of the principal objects of my invention is to provide a temporarybinder which will be adaptable to contain a plurality of 35publications. A'further object is to provide between the volumes aseries of index sheets which are normally fixed with relation to thevolumes, but which may be moved longi-.

tudinally of the binder so as to avoid overlapping of the data on theindex sheets; a further object is to provide means for holding the boundor folded edge of the volumes in fixed relation to the back of thebinder 5 when the binder is opened for reference; a further object is toprovide means whereby the binder may be permanently attached. to anupright support, such as a wall or telephone booth, and whereby thebinder will be suspended by flexible means to he parmoved therefrom forchanging.

allel with the wall. and yet have a range of elevation greater than thelength of the flexible suspension means, since long chains or cords havebeen found very undesirable.

Vith the above mentioned and other objects in view, the inventionconsists in the novel construction and combination of parts hereinafterdescribed, illustrated in the accompanying drawings and pointed out inthe claims hereto appended; it being understood that various changes invthe form, proportion, size and minor details of construction within thescope of the claims may be resorted to without departing from the spiritor sacrificing any of the advantages of the invention.

To more fully comprehend the invention, reference is made to theaccompanying drawings, wherein- Fig. 1 is a perspective of theinvention.

Fig. 2 is a section on line 22 of Fig. 1.

Fig. 3 is a front elevation of the supporting member.

Fig. 4 is a cross section on line 44 of Fig.

Referring more particularly to the several views of the drawings,wherein like characters of reference designate corresponding parts, Arepresents a binder cover generally, havin sides 1, preferably of astill or rigid material, and joined to a back 2 by the usual flexibleconnections 3. Secured to the back is a plate i, which preferablyextends the length of the binder, as shown in Fig. 1. The plate 4 issecured to the cover back by any suitable means, such as rivets 6. Inspaced relationship on the back plate 4 are flanges 7 turned backreversely upon themselves, as at 8, said turned portion 8 having thereinelongated slots 9 substantially parallel with the back plate.

gt plurality of binder bars 10 of spring metalareprovided for loosepositioning of the ends thereof in the slots 9, as at 11. A portion ofsaid bars, preferably the alternate bars, as indicated 1060 are providedas binder bars, the remaining bars indicated 106 are provided to mountindex sheets 12, which frictionally engage the bars and are slidablethereon and may be entirely re- These index sheets 12 have an ovoidalloo 13 at one end and are preferably made of exible material, so thatthe transverse minor axis of the loop frictionally engage the rod and byreason of the major transverse axis of the loop not being in. engagementwith the rod there is suflieient play in the loop to provide yieldablesliding action of the index sheet relative to the rod. The end of theindex sheet which is bent upon itself to form the loop, as at 14, issewed, stapled or otherwise securely fastened to the sheet in any usualThe flange 7 at one end of the binder mounts an eyelet 15 which may berigidly or swivelly connected, and this eyelet has associated therewitha flexible means, preferably a link chain 16 by which the binder isconnected to a member 17 which in turn is slidably mounted on a slottedsupport 18 and the support 18 is in turn secured to a wall, desk, tableor other suitable object by means of screws 19.

The member 17 comprises a front plate 20 and a back plate 21 maintainedin spaced relationship by an intermediate plate 22, said front and backplates being of greater width than the transverse width of slot 23 so asto extend beyond the longitudinal edges of said slot, as best shown inFig. at, the plate 22 being of lesser width than the transverse width ofsaid slot, and having slidable contact with the sides thereof. Theplates 20, 2.1 and 22 are securely maintained in their superposedrelationship by a staple 2 1 which preferably has a'pair of prongs 25which pass through the said plates and are riveted on the rearward sideof the back plate 21, as at 26, the prongs of the staple 2st being insetto form a shoulder 27 to engage the front plate 20 to prevent itsforward movement.

The flexible member 16 is secured to the staple 2st at one end and tothe eyelet 15 at its other end. Thus a support for the binder isprovided whereby the binder may be used at any angle or any position,and providing also for the convenient movement thereof for referencepurposes without the necessity of a long suspension means, and at thesame time providing a means to prevent the binder from being removedfrom its intended place or stolen.

In operation of the binder, the bars 10 are removed from the binder bybowing them which draws the ends inwardly. The bars 10a are insertedbetween the leaves of a bound publication or fold of papers at the boundor folded portion and the binder rods re-positioned by bowing them inthe same manner as they were removed. The bars 106 are removed andreinserted in the binder in the same manner as bars 10a, but with theindex sheets mounted thereon, as above set forth. This ent provides forremovable index sheets and the offset spacing thereof, and for indexingbetween the bound publications, instead of between the leaves thereof.The bars 106 being parallel to and in abutment against the bound edge ofthe publication, provides means to prevent the bound edge of thepublication moving upwardly to ride against the side of the nextadjacent publication when the binder is opened.

Having thus described my invention what I claim and desire to secure byLetters Patent is i 1. In a binder of the character described,

the combination with a binder cover of a back plate attached to saidcover and having upwardly and reversely bent terminal portions, saidreversely bent terminal portions each being provided with an elongatedslot parallel with the plane of the back plate, a plurality of looselymounted spring rods extending between said terminal portions andextending into the slots thereof in side by side relationship and aflexible index sheet mounted on one of said rods so as to have yieldablefrictional engagement therewith and adapted to slide 1ongitudinally onthe rod and providing an ovoidal loop through which the rod extends, oneportion of the ovoidal loop being adapted to extend between the boundportions of publications mounted on the said rods.

2. In a binder of the character described, the combination with a bindercover of a back plate attached to said cover and having upwardly andreversely bent terminal portions, said reversely bent terminal portionseach being provided with an elongated slot parallel with the plane ofthe back plate, a plurality of loosely mounted spring rods extendingbetween said terminal portions and extending into the slots thereof inside by side relationship, and an index sheet adapted to be mounted onone of said rods so as to have yieldable frictional engagement therewithand adapted to slide longitudinally on the rod, said index sheet beingof flexible material having at one end thereof an ovoidal loopintegrally formed of the same material adapted to receive within saidloop one of said rods and grip the same frictionally and yieldably.

3. In a binder of the character described, comprising the combination ofhingedly connected cover members, a back plate attached to said cover atthe hingedly connected portion, said back plate having an upwardlyturned lug at each of its opposite terminal portions, said lugs beingadapted to engage a binder rod, a binder rod extending between saidterminal portions and being releasable at an end thereof from engagementby the lug at said end, and a flexible index sheet mounted on said rod,said index sheet having portions thereof extending in 0ppositedirections from the portion which engages the rod.

In testimony whereof I have signed my name to this specification.
